Comparing internal bifold door materials: Timber vs uPVC vs Aluminium

John Collins Managing Director

Author: John Collins - Managing Director

When you’re looking for internal bifold doors for your home, considering the right material for your new doors is important. Timber bifold doors are usually designed to be fitted internally. In some instances, uPVC and aluminium bifold doors are chosen but these materials are traditionally used for exterior bifold doors.

An interior bifold door will have different requirements to external bifold doors and each material has its own benefits and drawbacks. In this guide, we will discuss the factors you should consider when looking for the perfect internal bifold door for your home.

Quick summary: How do the materials compare?

Which materials are best for internal bifold doors?

Internal bifold doors have a different set of requirements to external bifold doors. For example, thermal efficiency is incredibly important for external doors to protect your home from the elements. This means they are usually fitted with double or triple glazing, which increases door depth.

Deeper doors take up more space when they are stacked, which can be a problem in smaller rooms where space is an issue. For internal bifold doors, double glazing is not necessary and can be seen as superfluous with increased costs (and loss of space).

Many uPVC and aluminium doors that are stated to be ‘internal’ are actually designed to be external doors. They contain a number of unnecessary requirements, which increases their price. This means you will pay for additional features that are not needed.

Vufold’s internal wooden bifold doors are specifically designed to be fitted internally. They can easily be fitted flush (at the same level as the floor) and do not contain unnecessary utilities such as door hardware or double glazing. Internal bifold doors have slimmer frames than external bifold doors to make sure they can be used easily as an internal door. Instead, they utilise new technology and designs to save space and create a modern look for your home.

Maintenance required for each material

Maintenance includes things like painting, repairing or replacing doors. Internal folding doors require much less maintenance than external doors, as they do not have to face intense weather damage.

What style can each material offer?

Style can be the deciding factor for a lot of people. You want your internal folding doors to complement the interior rooms. This can sometimes be tough to achieve, so it is worth physically seeing the material beforehand, to ensure you will have a match.

Glazing options for internal bifold doors

Internal bifold doors do not need double glazing. They can make the folding doors deeper which will take up precious room when they are stacked as well increase the weight (and price).

How durable is each material for internal bifold doors?

If your internal bifold doors will get lots of use, you will want to ensure the material will withstand it. Resistance to damage and general wear and tear is important to increase the longevity of your folding doors.

Timber uPVC Aluminium
  • Vufold doors use timber engineering to make doors that are much stronger than standard solid timber, increasing durability.
  • A strong and sturdy bifold material which doesn’t sacrifice appearance.
  • Vufold internal stainless steel hardware offers silky-smooth operation is fully adjustable and is cycle tested to the equivalent of 40 years opening and closing.
  • Resistant to damage but not structurally strong can feel flimsy
  • Hardware is usually of Low quality and is rarely adjustable.
  • Resistant to weather damage, which is great for external bifold doors but makes no difference when used inside the home.
  • A strong metal, meaning it can support thinner frames than the other choices, if that is the style you want to go for.
  • Robust hardware that is long lasting but rarely adjustable.

Cost comparisons

The cost of an internal bifold door will always be one of the main deciding factors for homeowners. If you are working on a budget, the cost will obviously dictate your choice. Some materials offer a wide price bracket, which means bifolds for any budget!

The cost of your internal bifold door will vary depending on:

  • Overall width of your folding doors
  • The material you choose
  • The finish you choose – fully finished, white primed, unfinished
  • The number of doors and configuration you choose


  • Cheaper option as not full of features not required
  • A wide variety of doors at every level of budget
  • Budget timber bifolds available
  • Some Vufold doors are more competitively priced than UPVC


  • A cheaper option
  • You get what you pay for in quality and aesthetic


  • By far the most expensive interior door
  • High manufacturing costs mean a higher cost
